help! galaxy s2 wont startSupport

My phone was working it showed low battery, and i plugged it for charging, when I checked again it was turned off so I tried to turn it on but it didnt, it shows the (samsung galaxy s2 gt-i9100) screen and then nothing happens.

I tried removing the battery, the sim and sd card and turned it on again, still the same problem.

I dont have any backup and I dont want to lose my data, any idea of what shall I do? my phone is unrooted shall I try rooting it?

I think I have nand rw corruption & i cant access recovery mode.
And I tried odin mode but it fails to load the kernal
What shall I do?
Also now its not charging and last time i tried to turn it on it showed caution triangle after (samsung galaxy s2 gt-i9100)

For a step-by-step guide with video on flashing stock firmware, see #1.7 of the Jelly Bean update - Dummies Guide. Also, as mentioned in the guide, ensure that you have enabled, "USB debugging", in Settings before attempting to flash firmware via Odin.

I didnt enable debugging mode and I dont think its enabled by default.
Is there a way to fix my phone?

Can you get into recovery mode (volume up, power and home) or download mode (volume down, power and home)

Cannot get into Kies, will not recognise the usb connection now, revocery has been done several times as instructed by Samsung on the phone, still just goes to the samsung logo screen.
thanks for your input. frustrated with it.
